The current efficiency and copper purity of ammonia slurry electrolysis are respectively over 90 % and % Copper concentrations were determined using a UV spectrophotometer Reduction of potassium cyanide usage in a consolidated industrial process for gold recovery from wastes and scraps J Clean Prod 142
·The results showed that when the initial pH was 3 the initial copper concentration was 5000 mg/L and the final pH value was controlled above the copper in the wastewater was almost completely removed and the final copper concentration was ± mg/L which meets the Chinese electroplating discharge standard mg/L GB 21900
2 ·Extracting gold from the mined rock is a complex process From the time that the ore hoisted from underground and enters the processing plant it takes up to five days before the process of smelting into gold bars can commence The barren slurry from which the gold has been removed is discarded onto the Tailings Storage Facility TSF or

·Gold mainly exits in the electrolyte and little gold can be electrodeposited Besides the results of XRD and SEM show that the obtained metal powder is mainly copper and copper powder particles are mainly dendritic On the basis of these results slurry electrolysis could be applied to the recovery of copper and gold from electronic component
·The processing characteristics of copper gold ores vary from ore to ore and are closely related to the mineralogical composition of the ore Based on composition the ores can be classified into porphyry copper gold ores containing pyrite porphyry copper gold ores with negligible pyrite content and altered supergene copper gold ores
·A novel alkaline copper slurry that possesses a relatively high planarization performance is investigated under a low abrasive concentration Based on the action mechanism of CMP the feasibility of using one type of slurry in copper bulk elimination process and residual copper elimination process with different process parameters was analyzed In addition we
·Here in this study CPU sockets were chosen as a representative electronic component to explore if slurry electrolysis can directly and simultaneously recycle copper and gold Four factors HCl concentration pulp density current density and reaction time were discussed in detail
·The viscosity of their copper ore slurry increased from to Pa s with the increase in solid concentration of muscovite from 0 to 30 wt % at a shear rate of 100 s −1; however with the increase in solid concentration of talc from 0 to wt % there was a slight increase in the slurry viscosity from to Pa s at a shear
Common impurities found in gold ore include silver copper iron and sulphur These impurities need to be separated and removed through various refining processes to obtain pure gold Refining Process Steps to Follow The initial step in the gold refinery process involves the extraction of gold ore from the ground
·However by far the greatest extension in the use of copper resulted from Michael Faraday s discovery of electromagnetic induction in 1831 and the way that the effect could be used to generate electricity The same principle was used to develop electric motors The electric lamp was invented by Sir Joseph Swan in 1860 and brought to a commercial design by
·Abstract Lower defectivity pattern loading effect and better stability of removal rate RR through soft pad polishing life time have been identified as key influencing factors in copper CMP process In order to meet the strict requirement novel copper barrier slurry is designed and developed as a consequence One of the biggest issue of soft pads in Cu
·Antimony has become an increasingly critical element in recent years due to a surge in industrial demand and the Chinese domination of primary production Antimony is produced from stibnite ore Sb2O3 which is processed into antimony metal and antimony oxide Sb2O3 The industrial importance of antimony is mainly derived from its use as flame
·Abstract： • Copper fractal growth was observed during WPCBs recycling by slurry electrolysis • Dendrites fractal growth could be controlled by additive during electrodeposition • Additive was proved to be an effective way to refine the copper crystal
